Abstract :
A 2.45 GHz passive RFID tag including a digital pressure sensor and its use in a mobile-phone-centric architecture for sensor networks are described. The combination of a low-cost remote-powered sensor tag and an open architecture makes possible a variety of ambient intelligence applications. The tag gathers power from the ISM band at 2.45 GHz and wireless pressure measurement is demonstrated at a distance of 42 cm with 0.5 W EIRP transmission power and 110 cm with 4 W. The sensor is able to carry out pressure measurement with a 12-bit-resolution and a 100 Hz reading frequency.
